One button makes selections in field(s) resulting in only null-values in Year and Month (all possible values are gray).
The next button make use of Date so I have to click it twice, the first time makes Year and Month selectable (white) and the second time actually makes selection in field(s).
Action Clear all don't do the trick. Tried with a transparent button on top of the actual that should trigger the second one, but activate action is not the same as push button...
